Abstract
PURPOSE:To scan the reproduction of a read pattern at a uniform speed, by providing a read head having a sensor for reading a read pattern, and a sensor for detecting a position mark of a scale, and reading both the read pattern and the position mark simultaneously. CONSTITUTION:On a read head 1 for optically recognizing a pattern such as a character, a code, etc., a scale 2 which has displayed a reference position mark at prescribed intervals in accordance with scanning of the head is provided, and the head 1 is guided by a rail 3 installed to the scale 2 so that it can run in parallel with the scale 2. Also, a mechanical or electrical slit 4 is opened on the lower surface of the head 1, the slit 4 is moved automatically in the direction meeting at right angles with the rail 3 at a constant speed, and a position mark 6 of the scale 2 and a pattern 7 such a character, a code, etc. are read at the respective parts of read sensors 5A, 5B. In this way, the pattern 7 and the mark 6 are read simultaneously, and even when a scanning speed is not uniform, the reproduction of a pattern is scanned at a uniform speed.
